BENJAMIN H. KELLOGG, OF SHERMAN, CONNECTICUT.

SPECIFICATION forming part of Letters Patent No. 767,820, dated August 16, 1904.

Application filed April 25, 1904.

To all whom, it Wmty concern:

' Be itknown that I, BENJAMIN H. KELLOGG, a citizen of the United States, residing at Sherman, county of Fairfield, State of Connecticut, have invented a new and useful Device for Attaching Vvhiflietrees to Cross-Bars, of which the following is a specification.

My invention has for its object to provide a simple and inexpensive device for attaching a whifiietree to a cross-bar or evener which shall be adapted to attach a whiflietree of any thickness to a cross-bar or evener of any thickness and which, while leaving the whiffietree free to oscillate in the horizontal plane, will hold it against any oscillation or swingingwhatever in the vertical plane, it being of course understood that movementof the whiffletree in the vertical plane produces an undue strain on the whiflletree-bolt and is not infrequently the cause of breakage of whiflletree-bolts.

' With these and other objects in view I have produced the novel device for attaching whiffletrees to cross-bars and eveners which I will now describe, referring to the accompanying drawings, forming a part of this specification, and using reference characters to indicate the several parts.

Figure 1 is a plan view of my novel device, illustrating its application in attaching a whiffletree to a cross-bar; Fig. 2, a similar view illustrating its application in attaching a whiffletree to an evener; Fig. 3, a front elevation, on an enlarged scale, showing the device in use in attaching a whiflietree to an evener, and Fig. 4 is a section on the line a 4 in Fig. 3.

1O denotes shafts of ordinary construction for a single wagon; 11, a cross-bar therefor; 12, a pole for a double wagon; 13, an evener therefor pivoted to the pole, as at 1 1, and 15 a whifl'letree, which may be of any ordinary or preferred construction and is shown as provided with the usual strengthening-plates 16 at top and bottom.

My novel device comprises simply upper and lower plates (denoted, respectively, by 17 and 18) a guard-plate 19, a bolt 20, and an ordinary whiflietree-bolt 21. It is an essential feature of the invention that the three Serial No. 204,686. (No model.)v

plates are made independent of each other, so as to adapt the device for use with any thickness of cross-bar or evener or of whiffletree. Plates 17 and 18 lie above and below the crossbar or evener, the upper plate being preferably extended forward, as at 22, in order to give increased strength and also to form a convenient rest for the whiffletree in assembling. Bolt 20 passes through the guard-plate, the cross-bar or evener, and through both upper and lower plates. Just forward of the head of the bolt the guard-plate is curved upward and then forward to partly inclose the whiffletree, as clearly shown in Fig. 4. These guard-plates are formed for the market of average height and may be made of difi erent sizes or may be slightly shaped at the time of use to adapt them for slightly thicker or thinner whiflietrees. The whiflietree, as already stated, rests upon the upper plate 17, and the forward end of the guard-plate lies just above the whifiietree, inclosin g the top and back of the whifiletree, the whifiietree being given just sufficient room to permit it to oscillate freely. The whiffletree-bolt passes through the guardplate, the whifl'letree, the upper and lower plates, and down in front of the cross-bar or evener, as clearly shown in Fig. 4, so that the cross-bar or evener is not weakened by ahole for the whiflietree-bolt, the strain upon the evener being taken up by bolt 20, which passes through the cross-bar or evener near the back thereof. 7

Having thus described my invention, I claim- 1. A device for attaching whiflietrees to cross bars or eveners, comprising plates adapted to lie above and below the cross-bar or evener, a guard-plate above the evener shaped to partly inclose the whiifletree, a bolt adapted to pass through the guard-plate, the upper and lower plates and the cross-bar or evener and a whiiiletree-bolt adapted to pass through the guard-plate above the whiffietree, through the whifiletree and the upper and lower plates and in front of the cross-bar or evener.

2. A device for attaching a whifliietree to a cross-bar or evener comprising upper and lower plates Adapted to lie on opposite sides the Whifiletree and the upper and lower plates T0 of the cross-bar or evener, aguardplate above and in front of the cross-bar or evener. the upper plate and curved upward and for- 1 In testimony whereoflaflix my signaturein ward to partly inolose thel whiflleltrele, abbollt I presence of two Witnesses.

5 adapted to pass through t 1e guar -p ate ac l of the whifiletree and through the upper and BENJAMIN KELLOGG' lower plates and the cross-bar 0r evener, and a whifil etree-bolt adapted to pass through the guard-plate above the Whifiletree and through I I Witnesses:
